一种基于3层C/S结构的电能量计费管理系统

AN ENERGY BILLING MANAGEMENT SYSTEMBASED ON THE THREE^TIER CLIENT/SERVER MODEL

开发了一种基于 3层 C/ S结构的电能量计费管理系统 ,该系统通过公用数据通信网将各电厂采集的电能量数据远程传输到控制中心 ,由控制中心进行计费、查询、生成报表、数据分析等处理 ,并以 Web方式发布在 Internet上供用户查询。详细介绍了系统的目标、结构、工作原理和功能 ,分析了 3层 C/ S结构应用程序的优点和工作原理 ,并给出了采用 Delphi实现这种 3层 C/

In the developed energy billing management system, the energy data are transferred from power plants to controlcenter by common data communication network. The work of billing. querying, generating report and data analysis and so onare all done in the control center. The energy information is released in the internet with Web mode. Then the paperintroduces the object, structure, working principle and functions of the system. The merits and principle of three-tier Client/Server (C/S) application is analyzed. The method to realize the three--tier C/S structure with Delphi is given at last.
